Amine and tin fluoride inhibition of Streptococcus sanguis adhesion under continuous flow

This study evaluated the ability of topically applied amine fluoride (AmF) and AmF-tin fluoride to inhibit the adhesion of Streptococcus sanguis withi n a parallel plate flow cell system. One of three AmF compounds and two tin fluoride preparations significantly reduced the net bacterial adhesion to conditioned glass over a 1-h period. Tin(IV) fluoride inhibited S. sanguis adhesion to the greatest extent, and this was shown to be dependent on the formation of the conditioning film prior to agent application.
